In precision viticulture, bunch morphology affects the quality of the grapes, and subsequently the wine. Methodologies to objectively and fast evaluated related traits is a pending task within the food industry context.                                                                                                                    In this study, we developed a novel high-throughput phenotyping pipeline based on structure light depth-sensing from point clouds acquired by HP 3D Structured Light Scanner Pro S3 of grapevine bunches under lab conditions. For that, a bunch was scanned to provide not only bunch architecture traits but also individual berry characterization by combining 3D modelling and machine learning algorithms.                                                                                                    The quality of the results provided by a visual inspection gives clear promises to breeders to improve the phenotypic selection in an environmentally and economically way.
